"Because in addition to being long-lasting and stable, the earth fire is much stronger than the ordinary true fire in terms of the success rate of refining pills, not only alchemy, but also refining tools have the same effect. Therefore, in fact, some immortal cultivation sects with better conditions or larger-scale immortal cultivation families will have exclusive yang fire lands, which are used to attract the underground flames and supply the disciples in the clan to refine the alchemy. Generally speaking, in this era, there are not many low-level immortal cultivators who still use true fire to refine pills. After a pause, Hua Chi added.

"Of course, the most important reason for this is that if you need to refine the pill, you must use flames, and not every immortal cultivator contains fire spirit roots...... Therefore, after a little comparison, the advantages and disadvantages are immediate. In other words, in order to provide a panacea that satisfies the needs of a sect, the use of earth fire is essential. Only in this way can more disciples participate in the matter of refining medicine. Between the words, Hua Chi took a few steps forward, walked to the furnace of the house, and said slowly.

"In that case...... Is this house equipped with a device that can lead the flames from the ground up like water, and can be used freely? After walking a few steps, Luo Xiaoli, who stopped next to Huachi, thought about it and said.

"Well, Senior Sister Xiaoli, these beast head carvings are the ground fire mouth of this medicine refining room, and the earth fire that needs to be used when refining the pill is spewed out from here, and it can also be adjusted according to the strength of the flame according to the need." The probe pointed to the four fierce beast heads inlaid on the stone pier, and Hua Chi introduced it again.

After speaking, Hua Chi turned his head to look at the walls on both sides again, and said: "One of the very important reasons why these two walls are different from ordinary walls is that the flames that exist in the deep underground such as earth fire, want to draw out and take it for their own use, in the eyes of some powerful immortal cultivators, it is not difficult, but if you want to lead from the underground to the current mountain peak, it is obviously a little beyond the ordinary category, if one is not good, it is very possible that the entire mountain peak will be destroyed by the earth fire." ”

"Huh? Could it be that these two walls are the key to preventing this from happening? After hearing this, Luo Xiaoli, who suddenly had a flash of inspiration, replied. Don't look at the fact that since the initiation ceremony, she often seems to be a little confused, but she is actually very smart.

This can be known from the fact that he has been dealing with Wang Shuai for more than half a year and has not let the other party succeed. Although the master is often in the cave, it is one of the reasons why he is difficult to be ruthless.

"Sister Xiaoli is right. These two walls look ordinary, except for the color, they seem to be similar to the other walls, but if you pay close attention, it should not be difficult to see that the walls here are very different from other places in terms of materials. After nodding, Hua Chi walked to the wall again, turned his head and said.

"Oh......."

After listening, Luo Xiaoli also approached in three steps, and then reached out to touch it, but found that the material of this wall was indeed different from what she usually encountered, not only did it look rough, but once it was touched, it was extremely smooth, and there was a cold and cold power faintly revealing inside, which seemed to be able to restrain each other with flames, which was very wonderful.

"This kind of stone, called the Flint Stone, is produced in a sixth-level country called Yunshui Country. Although it is not too rare for them to be called a rare thing, it is indeed a rare thing in our Tianyan Kingdom. And the fact that these walls could be built and successfully lead the earth fire from the depths to the top of the mountain was all due to the two of them, the sect master and Elder Song Yu. If it weren't for the fact that the two of them had been collecting all the flint stones they needed in the Yunshui Country for several years, it would not have been possible for our Luoyun Sect's Alchemy Hall to make a qualitative leap all at once. Therefore, from now on, it was not unreasonable that the Alchemy Hall would be in charge of Elder Song Yu. As he spoke, Hua Chi couldn't help but look at it, no matter who looked at it, it was not difficult to see that this beautiful woman was a supporter of Elder Song Yu.

On the other hand, Luo Xiaoli, after listening to these words, she nodded in understanding and did not make a sound.

Speaking of which, in Luo Xiaoli's world, in this piece of heaven and earth, there are countless immortal cultivation realms and sects. But under this, over time, there is a kind of hierarchical division that appears and arises. Therefore, every country now has a corresponding level, for example, the Tianyan Country where Luo Xiaoli is located is a seventh-level country.

Level 7 ...... This level is directly linked to the powerful immortal cultivators that have appeared in the country, and the Tianyan Council is at the seventh level, because of a peerless powerhouse many years ago, the Medicine Emperor!

A powerful existence that can walk sideways in the purple level.

Therefore, the cultivation level of immortal cultivators corresponds to the level of the country.

The Yunshui Kingdom is level six, which means that there has never been a purple-level terrifying figure in this country for many years, and the highest cultivation level is only a blue-level Venerable, and so on.

As for some countries where the aura of heaven and earth is frighteningly thin, it is natural that they can only get out of some qi refining cultivation, at most they are foundation building cultivation, such red-level and orange-level immortal cultivators exist as first- and second-level countries.

But then again, although the Tianyan Kingdom walked out of a figure like the Medicine Emperor many years ago, after the Medicine Emperor, there was no new purple-level powerhouse born for a long time. Even Yun Xuanzi, the sect leader of the Falling Cloud Sect, the strongest sect in the Heavenly Flame Country, was only a blue-level six-star cultivator, and he didn't even have the qualifications to try to attack the purple level.

Therefore, in essence, Tianyan Kingdom only has the title of Seventh-level, and in terms of strength, it is still at the level of Sixth-level, which is the bottom of Seventh-level countries.

While Luo Xiaoli was thinking about this, Hua Chi on the side had also recovered from his reverence for Song Yu, looked at this junior sister who didn't know what she was thinking, and said softly: "Senior sister Xiaoli, as I just introduced, it is best to take it step by step in the matter of learning alchemists. According to the three conditions of the alchemist, the first thing you need to learn is about the flame problem during refining. ”

"Flames? Senior Sister Hua Chi, I don't know how this flame should be manipulated, what mechanism should be opened directly, or ......? The little face wrinkled, and Luo Xiaoli, who didn't seem to figure out how to solve the problem Hua Chi said, asked back.

"Senior Sister Xiaoli, of course we don't use any mechanism or anything like that, it's a mortal method, and we, as immortal cultivators, naturally use supernatural powers." Smiling slightly, Hua Chi touched Luo Xiaoli's little head with his hand and said.
